Standard question: are you using media-ctl from
git://linuxtv.org/pinchartl/v4l-utils.git field branch and latest
yavta from git://git.ideasonboard.org/yavta.git ?

No, not exactly. I used older versions which came with Yocto Poky Daisy.
But I also tried with these newer ones and get the same:
root@overo:~$ ./media-ctl -v -r -l '"tvp5150 3-005c":0->"OMAP3 ISP
CCDC":0[1], "OMAP3 ISP CCDC":1->"OMAP3 ISP CCDC output":0[1]'
